This purification method is applicable to the above-mentioned purification device, and this purification method further includes the following operating steps: Step 1: The staff adds the prepared ferrous sulfate, deionized water, and phosphoric acid into the inner barrel 3. The first rotating motor 15 drives the threaded rod 16 to rotate. The lifting member 13 moves up and down in the second slot 24. The lifting member 13 descends to the preset use position.

The lifting member 13 moves upward until the bottom of the positioning plate 14 below the lifting member 13 is at the same horizontal height as the bottom of the pressing plate 7.

[0033] When the present invention is in use, the electrical equipment used in this device is all powered by connecting to an external power source through wires. This device controls the electrical equipment in the device by setting a control system. The filter plate 33 used in this device is an existing mature technology, so it will not be elaborated further here. When the device is in use, solenoid valve switches are installed at the bottoms of the first discharge hole 8 and the third discharge hole 34. The solenoid valve switch is an existing mature technology, so it will not be elaborated too much here. The bottom of the second discharge hole 9 is connected to a waste collection bucket through a conduit, and the bottom of the support leg of the outer barrel 1 is fixedly installed through bolts in the preset holes on the ground.

[0034] When the device is in use, the electric lifting rod 6 drives the pressing plate 7 to move upward until the bottom of the pressing plate 7 disengages from the inside of the inner barrel 3 and moves to the preset use height position. Subsequently, the staff adds ferrous sulfate, deionized water, and phosphoric acid prepared by tools into the inner barrel 3. Then, the first rotating motor 15 drives the threaded rod 16 to rotate, so that the lifting member 13 can move up and down in the second slot 24. When the lifting member 13 descends to the preset use position, the rotating motor 12 drives the pressing plate 7 to rotate, so that the lifting member 13 can stir the solution in the inner barrel 3; During the rotation of the pressing plate 7, the second rotating motor 29 drives the rotating plate 21 to rotate. The way that the second rotating motor 29 drives the rotating plate 21 to rotate can, during the process of the lifting member 13 stirring the solution, increase the stirring range of the lifting member 13 for the solution by rotating the rotating plate 21 to different use angles. And through this operation method, the stirring rate of the lifting member 13 for the solution can be increased, making the solution mix more evenly and increasing the use convenience of the device.

[0035] After the solution is stirred, the staff adds a purification reagent into the inner barrel 3. The purification reagent is an existing mature technology, so it will not be elaborated further here. Then, the solution is stirred again through the above operation method. After stirring to the preset degree, the rotating plate 21 rotates to the use state as shown in Figure 9 Figure [not shown]. Subsequently, the lifting member 13 moves upward until the bottom of the positioning plate 14 below the lifting member 13 is at the same horizontal height as the bottom of the pressing plate 7. The solution in the inner barrel 3 generates precipitation. After the precipitation reaction is completed, the solenoid valve switch at the bottom of the third discharge hole 34 is opened. The reacted solution in the inner barrel 3 passes through the filter plate 33 and flows through the third discharge hole 34 and into the inner part of the outer barrel 1 for collection. The solution in the outer barrel 1 is the mother liquor required by the staff. By opening the solenoid valve switch at the first discharge hole 8, the mother liquor collected in the outer barrel 1 can be discharged. The staff can obtain the required purified iron phosphate by further processing the mother liquor. The further processing method of the mother liquor is an existing mature technology, so it will not be elaborated too much here; During the process of the solution being filtered through the filter plate 33, the electric lifting rod 6 drives the pressing plate 7 to move downward, so that the pressing plate 7 moves downward inside the inner barrel 3. By pressing the solution in the inner barrel 3 with the pressing plate 7, the falling speed of the solution from the filter plate 33 can be accelerated. At the same time, through this operation method, the pressure filtration of the residue can be realized, so that the mother liquor in the solution residue in the inner barrel 3 quickly flows into the outer barrel 1 for collection, increasing the use convenience of the device.

[0036] After the pressure filtration of the solution in the inner barrel 3 is completed, the pressing plate 7 moves upward out of the top of the inner barrel 3 and moves to the preset height use position. Subsequently, the filter plate 33 is driven to move upward by the electric extension rod 35 until the top of the filter plate 33 moves to the same horizontal height position as the top of the inner barrel 3. By sliding the moving electric slider 11 in the moving chute 10, the pressing plate 7 moves to the side away from the outer barrel 1. After the pressing plate 7 moves to the preset use position, by sliding the movable electric slider 28 in the movable chute 27, the movable plate 23 moves out of the inside of the first slot 22 until the bottom of the movable plate 23 moves to the same horizontal height position as the top of the inner barrel 3. Subsequently, by sliding the moving electric slider 11 in the moving chute 10 again, the pressing plate 7 moves in the direction of the outer barrel 1. When the movable plate 23 at the bottom of the pressing plate 7 passes over the top of the inner barrel 3, the filter residue on the filter plate 33 can be scraped into the inside of the collection ring 2 by the movement of the movable plate 23. Subsequently, the filter plate 33 moves to the bottom of the inner barrel 3 again. By this operation method, the automatic discharge of the filter residue on the filter plate 33 can be realized, increasing the convenience of use of the device; By sliding the annular electric slider 18 in the annular chute 17, the push plate 20 can be driven to move inside the collection ring 2, so as to push the filter residue inside the collection ring 2 to the second discharge hole 9 for discharge, increasing the convenience of use of the device.

[0037] After the device is used up, by moving the lifting member 13 into the inner barrel 3, and then by rotating the rotating plate 21 and extending the cleaning block 31 out of the third slot 30, the cleaning brush on the cleaning block 31 can abut against the inner wall of the inner barrel 3.
